Auggie will pee on cue too - it amuses people when I say "No, I made him pee before we left the house."
My grandma thinks it's hilarious that Auggie knows (and gets SUPER EXCITED) about "go brush your teeth???"
He knows stuff like "Walk straight" and "cross the street" and "turning here" when we're on our walks, because we often take different routes and I tell him which way we're going because I'm weird and talk conversationally to my dog like that.

And one that he recently has learned... "Just because another dog is barking doesn't mean you have to bark too." I started telling him this offhandedly and conversationally, but now he's apparently learned it as a "quiet down and settle down" kind of cue. (Learning to react to weird, long strings of words like this is why some people swear shelties must really know how to speak English. =P)

I guess it might not count since I don't really "teach" him stuff, he just kind of picks up on things that I repeat often enough and with certain body language and tone of voice...

Tenebrion, mine are similar to yours. Most of mine are in German, though.
Some of the ones I get weird looks for:

Crate Up: She goes into her crate and waits for my release command before coming out. Though, I said "Chillax" for Shep.

Raja sits and waits for "Nimm Futter" before she eats. She sits and waits for either "Geh Raus" before going outside or "Geh Rein" before going inside. Though, we have not yet mastered those when other people are present. I usually have to actually TELL her "sitz" in that case. And sometimes I have to say it a few times.

We're currently working on "Lass Es" aka Leave It, which makes her move away from what she is getting into and come sit in front of me until released. That was usually the one people thought I was cruel for teaching Shep, though I've no idea why.

I think those are really the only ones I get odd looks for. Oh, and most people find it an odd choice that my release command is "At Ease." lol
